可以避免全局被使用（需要typeName）；

    传字典：需要归档

    NSDictionary *dic = @{@"name":@"哈哈碉堡啦",@"image":[UIImage imageNamed:@"qq"]};

    UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];

    NSData *dictData = [NSKeyedArchiver archivedDataWithRootObject:dic];

    [pasteboard setData:dictData forPasteboardType:@"AType"];

    接收：

    UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];

    NSDictionary *dict = [NSKeyedUnarchiver unarchiveObjectWithData:[pasteboard dataForPasteboardType:@"AType"]];

    NSString *name = [dict objectForKey:@"name"];
